Data sources PubMed, Cochrane Library/Embase and Web of science.
Study selection Randomised controlled trials and non-randomised trials reporting success or failure rates of direct restorative materials for managing root caries lesions and in vitro studies assessing performance of restorations for root caries lesions published between September 1990 and October 2021 and written in English were included.
Data extraction and synthesis Data was extracted by one reviewer and quality assessment of the included clinical studies performed using the Cochrane risk-of-bias in non-randomised studies of interventions tools. Restoration success, survival and failure rates were presented for each included study with no data synthesis.
Results A total of 11 clinical studies and 31 in vitro studies were included. Restoration failure rates ranged from 14-55% at 24-60 months. Success rates of atraumatic restorative technique (ART) ranged from 65-87% at 12-60 months.
Conclusion There is a lack of high-quality evidence to provide a recommendation on the most appropriate restorative material for restoring root caries lesions. The survival rate of ART and conventional techniques are comparable and ART could be an optional treatment where conventional treatment is challenging.
